Case ReportsGastroplasty for esophageal perforation after endoscopic balloon dilatation for achalasia: two cases.
Esophageal perforation after endoscopic forceful pneumatic dilatation for achalasia is a devastating complication and surgical treatment is necessary. A 65-yr-old man and a 54-yr-old woman referred for esophageal perforation two hours after pneumatic dilatation and during the procedure, respectively. Gastroplasties through thoracotomy were performed in both cases and their recoveries were uneventful. ⋯ On the follow-up endoscopy 4 to 6 months after operation revealed that reflux esophagitis of LA classification A were noted in the both patients. They did not complain any reflux symptom or dysphagia for 9 to 13 months after operation. Instead of the most widely used procedure; primary repair of perforation site, wrapping with intercostal muscle flap and esophagomyotomy, gastroplasty was performed in two cases of iatrogenic esophageal perforation in achalasia and experienced good results.

The relationship between J wave on the surface electrocardiography and ventricular fibrillation during acute myocardial infarction.
We investigated whether the presence of J wave on the surface electrocardiography (sECG) could be a potential risk factor for ventricular fibrillation (VF) during acute myocardial infarction (AMI). We performed a retrospective study of 317 patients diagnosed with AMI in a single center from 2009 to 2012. Among the enrolled 296 patients, 22 (13.5%) patients were selected as a VF group. ⋯ We also confirmed that several conventional risk factors of VF were significantly related to VF during AMI; time delays from the onset of chest pain, blood concentrations of creatine phosphokinase and incidence of ST-segment elevation. Multiple logistic regression analysis demonstrated that the presence of J wave and the presence of a ST-segment elevation were independent predictors of VF during AMI. This study demonstrated that the presence of J wave on the sECG is significantly related to VF during AMI.

Meta AnalysisPapillary thyroid microcarcinomas are different from latent papillary thyroid carcinomas at autopsy.
The aim of this study was to review the literature of latent papillary thyroid carcinomas (PTCs) discovered at autopsy and describe the available pathologic and demographic differences from a group of papillary thyroid microcarcinomas (PTMCs) the reported in a previous publication. We searched the PubMed for published articles describing latent thyroid carcinomas detected at autopsy. Meta-analysis was performed to identify differences between the clinicopathologic features of PTMCs analyzed previously in our institution (Group I) and those of latent PTCs described in autopsy studies (Group II). ⋯ The rates of multifocality were 24.7% in Group I and 30.5% in Group II, and the rates of cervical lymph node metastasis were 33.4% in Group I and 10.0% in Group II. Currently available data indicated that clinically evident PTMCs differ from latent PTCs detected at autopsy. Therefore, these two entities should be regarded as different.
